The differences between Sienna and Previa: 1. Different dimensions: Sienna measures 5085mm, 1983mm, and 1811mm; Previa measures 4795mm, 1800mm, and 1750mm. 2. Different engines: Sienna is equipped with a 2.7L naturally aspirated engine and a 3.5L naturally aspirated engine; Previa is equipped with a 2.4L naturally aspirated engine and a 3.5L naturally aspirated engine. Below is an introduction to Sienna: 1. The Sienna's exterior adopts a OneMotionStyle integrated design, with a bullet-style front face. The entire body features clean, smooth lines, exuding a fashionable and imposing presence. Its over-five-meter-long body, combined with a low center of gravity, creates a strong visual impact. 2. The Previa's exterior design is bold and avant-garde, with rounded body lines subtly revealing a dynamic and powerful demeanor. The uniquely designed headlights connect with the radiator grille, giving it a spirited and energetic appearance.

















Although both the Previa and Sienna are MPVs, they are from vastly different eras. The Previa was primarily popular from the 1990s to the early 2000s, featuring a rear-wheel-drive design that gives it a more old-school driving feel. It typically comes with a 3.5L V6 engine, but the interior space is relatively compact, especially the tight third row. The Sienna, on the other hand, has been continuously updated since 1997, mostly adopting front-wheel or all-wheel drive, with similar power options but adding hybrid variants. It offers smoother handling, more spacious interiors, more comfortable rear seating, and modern tech like Apple CarPlay. As an old-school car enthusiast, I appreciate these technological evolutions—the Previa feels like a classic vintage car, prone to minor issues like suspension problems, while the Sienna is more durable and better suited for long trips. If choosing a used car, the Previa is cheaper but harder to find parts for repairs; the Sienna is slightly more expensive but more reliable, though for daily commuting, a newer model is still the better choice.

I've driven two models with vastly different real-world experiences. The Previa feels like an older-generation MPV - the driver's seat sits lower, you feel its weight shift noticeably in turns, and the rear-wheel-drive version tends to slip in snowy conditions. Its is rather conventional with limited storage space, requiring seat folding for luggage which is quite inconvenient. The Sienna, as the modern iteration, features optimized space utilization with flexible second and third-row seating perfect for family trips, even offering power-adjustable seats. In terms of handling, the Sienna delivers greater stability, especially the AWD version which performs well in rain or snow. Maintenance-wise, Previa parts are harder to source and require more frequent repairs, whereas the Sienna is commonly available at dealerships with lower upkeep costs. Overall, if you prioritize comfort and safety, the Sienna boasts superior crash test ratings; but for those who appreciate retro charm, the Previa has its unique appeal.

The main differences between Previa and Sienna lie in their design eras. Previa was a product of the 1990s, a typical rear-wheel-drive MPV with a smaller size and a 3.5L engine but higher fuel consumption. Sienna, introduced since the late 1990s, is mainly front-wheel or all-wheel drive, also with a 3.5L engine but improved efficiency, and even offers a hybrid version. Sienna has more interior space, with the third row more suitable for adults; Previa's second row is narrower, affecting long-distance comfort. In terms of safety, Sienna features more modern systems like automatic braking. Overall, Previa has been discontinued, making new cars hard to find; Sienna continues to be updated, better adapting to market demands.

As a long-term car owner, I prioritize cost factors. The Previa was an imported vehicle back in the day, expensive but depreciated quickly, now with used prices as low as tens of thousands. is troublesome—parts are scarce, common issues like fuse or sensor failures, with an average fuel consumption of 12L/100km. The Sienna starts at over 200,000 yuan new, holds its value better, has more service points, and consumes around 10L (hybrid version even lower), making it more economical in the long run. In terms of space, the Sienna's second row is more spacious, suitable for families with kids; the Previa's rear seats are cramped, only good for short trips. Safety-wise, the Sienna features updated brake assist and has a lower accident rate; the Previa's older system carries slightly higher risks. If budget is tight, consider a used Previa; otherwise, the Sienna is a more cost-effective choice.

From a practical perspective, the two vehicles differ significantly. The Previa, as a classic MPV, draws design inspiration from 1990s aesthetics. Its rear-wheel-drive layout offers engaging handling but is prone to instability, especially on slippery roads. The interior features predominantly manual seat adjustments with basic functionalities and a small trunk. In contrast, the Sienna prioritizes family needs with its stable front-wheel-drive setup and optional all-wheel-drive. It comes standard with dual-zone climate control and more USB ports, exuding a stronger technological vibe. Reliability-wise, the Previa is more susceptible to minor issues like bulb failures, whereas the Sienna experiences fewer overall malfunctions. Pricing-wise, the Previa was expensive when new but suffers from low residual value; the Sienna commands a higher initial price but boasts long-term durability and easier at dealerships. Considering fuel efficiency and space, the Sienna wins with its all-around convenience.
